    hi,

    [See Signature for my config]

    i undervolted my T7250 with RMClock, and could cut off ~10° Celsius. but i still have some questions. first, the pictures of my config.

    1. "Advanced CPU Settings -> Auto-Detect" -> results in "Desktop", not "Mobile" !

    2. are the "Professional Features" worth registering?

    3. what about "Run HLT when OS is idle", do I need it?
    and is the hlt command the same like another process with 100% usage, or is for example Prime95 more power consuming than the HLT command?

    4. my graphics card 8400 GS reaches 60°C , when CPU is only 45°C. is this strange?

    1) Choose Mobile

    2) No, the extra features are useless. See the RMclock website for the what prof version does

    3) Just follow my guide on sig. Your voltages arent detected correctly

    4) No, the cpu will recieve better cooling than the GPU

    I strongly suggest you read my guide

    1) Does it matter? Choose the right one.

    2) Check the website for the differences.

    3) Making the CPU execute the HLT command over and over is an old method of power conservation. HLT would force the CPU into a low-power state which it would wake up from when something needed its attention (technical terms like Interrupts appear at this point in my explanation - alienating most people reading this thread, so I'll skip it). Don't choose this option.

    4) CPU's run cooler than GPU's. GPU's tolerate higher temps (up to 90 degrees C for most newer nvidia chips) because they are generally based on >65nm technology and are less intricately designed than CPU's. GPU process technology somewhat lags behind that of CPU's.
